The Evaluation of Osseointegration of Dental Implant Surface with Different Size of TiO2 Nanotube in Rats

Figure 9

The removal torques mean value at 2 weeks (a) and 6 weeks (b) after implantation. TiO2 nanotube surface-treated groups showed higher value than the control group (nontreated group). 30 nm experimental group and 70 nm experimental group at 2 weeks and 6 weeks showed the highest value, respectively ().
